Root code execution via SOAPAction buffer overflow
Published Mar 29, 2023 · Updated Feb 18, 2025
Buffer overflow in NETGEAR R6700v3 1.0.4.120_10.0.91 allows network-adjacent attackers to execute arbitrary code through crafted SOAP requests. The upnpd SOAP parser copies the user-controlled SOAPAction header into a fixed-size buffer without validating its length. Exploitation requires the WiFi password or an Ethernet connection and executes code in the root context.
